. in Combination Phonographs and Picture- Reproducers, of which thefollowing is a specification.

ThlS invention relates to a device essentially adapted for attachment toa pheno graph and it is designed to project a picture on a screendepicting a sequence of events.

The object-of the invention is to provide" the sound reproducing machinewith a disk having pictures photographed in spiral for-' mation thereon,and means connected to the phonograph actuating devices for moving thelens in unison with the pictures por-' trayed on the screen. Theinvention comprehends devices -c 0nneoted to the picture disk operatingmeans for controlling the movement of the lens'so that it will be timedto move in unison relative to the progression of the pictures in theireccentrlc revolution about the axisof the disk. In other words it is thefundamental object of these devices to actuate the lens step by step toregister with each picture from the outer radius of the spiral to itstermination near the axis of the disk.

- The other objects of the invention will be more fully described in thefollowing specification and claims and illustrated in the accompanyingdrawings, forming part of this specification, in which Figure 1represents a side elevation of a phonograph embodying this invention.

Fig. 2 represents a front view thereof with the screen removed.

Fig. 3 represents a plan view thereof with parts broken away.

Fig. 4 represents an enlarged horizontal view of the lens feeding arms,partly in section; j

Figs. 5 and 6 represent cross-section's taken on line5 5 of Fig. 3 andshows the teeth of the feeding arms engaging the master disk indifferent positions. 1

The invention, as shown in thedrawings', is applied to a phonographwhich may be of any kind or manufacture, of the disk-record type. Theletter a designates the casing of the phonograph and has embodiedtherein an amplifying born I). The sound record carry mg plate 0 isrotated by the central shaft (1 actuated by the driving mechanism ormotor, not shown. The sound record 6 is carried by the plate a. Thereproducing arm f with its sound box 9 is mounted on the phonograph inthe usual way.

' To the casing a-of the phonograph are secured uprights h which areconnected to a horizontal frame i which serves as support for thepicture exhibiting and master disks with its connections. A brace 7' isfastened to the lower portion of the uprights h and serves as supportfor the screen is, onto which the pictures are projected. This screen ismade of translucent material, such as muslin or the like. It is to beunderstood that the osition of'the screen may be varied accord i to thefocal length of the lens.

To t e end of the shaft 61 is fastened or held in frictional engagementtherewith a spindle Z, mounted to turn in a bearing m fastened to frame2'. Above the bearing m is secured an intermittent ear 1:. with-onetooth, meshing into a muti ated crowngear o mounted to revolve in abearin glfastened to the frame 2'. At the back o t e gear 0 is a bevelgear a meshing into a small bevel gear'e fastened to a cam shaft wsupported at each end in bearings 12 and 13 fastened to frame 71. Atransmission shaft 9 is mounted to revolve in suitable bearings 10 and11 secured to frame 2'. At the front end of said shaft is fastened by athumb-nut or other suitable fastening device, so as to admit adjustment,a disk 1". This disk is made of lass or other suitable material and hasupon t e face thereof small positivephotographically produced pictures,arranged in a helical or-spiral path.

At the rear end of the transmission shaft 1? and in close proximity tothe rear portion of frame 2' is fastened a master-disk t, which isreferably made of tempered steel, having ho es t arranged in a helicalor spiral path. The center of the'holes as -well as the spiral path areidentical with the-center of the pictures on the picture disk 1',theobject of this to be explained later. 5

The-shaftw has a cam member w attached thereto for the cooperation of 2;lug 20 attached to a rocking arm 16 and at the end thereof adjacent tobearing 12 is attached a, collar 22. Its purpose will be explainedlater.

the bearing 13 and slightly below the tance between theholes,

' which is mounted in a bearing 17, formed in one end of a carriage 15,and is held in position by a collar 18. The rockin arms are adapted tostraddle the master (li'sk t. To the inside of the outer endsof the armsare fastened tapered pins 19, see Fig.- 4, which are radially inalinement with the focal center of the lens. The pins are'positioned oneabove the other at opposite arms verticall see'Figs. 5 and 6. To the arm16 direct y opposite pin 19 is'an outward projecting lug 20.

t will now be seen, that the spindle Z revolves with a uniform motionreceived from the motor. The interrupted gears 70. and 0 impacts anintermittent motion to'the camshaft 'w by reason of gears u. and 'v. Thecam 10' at each revolution comes in contact with the lug 20, will. causethe arms 16 and '16 to-rock to one side, andas soon as the cam is out ofengagement with the lug, the spring 21 which-is fastened to the underSldQ'Of the carriage 15, will return the arms to their first pos1tion.-I

By referring to Fig. 5, it will be seen that the hole marked t in thedisk t; is in alinement; with the camshaft w. It'is, therefore. also 1nalinement withthefocal axis of the lens. One of the pins19 has passedinto the hole above, and 1s holding-the disk firmly Whlle the pictureisthrown on the screen. When the cam w' comes in contact with the lug 20,the'pin above referred to is disengaged sald hole in the disk, and thelOWer pm w1ll enter a hole two spaces below, thereby moving the disk onehalf'the dis- See Fig.5. As soon as the can! has. disengaged the lug 20,the spring 21 returns the arms-to a position shown-in Fig. 5, and thedisk t will have moved the distance of one hole. It will also be seen,that the ins 19 are bent and form an are described m the center of rod14. The outer end of ward,

and as they come in contact with the lower portion of a hole and areforced into same, will cause the disk to move in the diintermittentmotion.

rection of the arrow.

Therefore, as the camshaft is rotated, the rocking arms will cause thepins to enter the holes 1n the disk and impart to same an: The pins willengage the holes successively and engage same in the splral path,thereby turning the two disks in unison and at the same time .therockmg'arms are also moved toward the axis of the disks. I

At the end of the spiral or when the last hole has been reached the lug20 will have passed the cam w and will be-in contact,

with the collar 22 On camshaft 1a the said pins are tapered down-4 armsin a neutral position and preventing any further movement of the disks.When the phonograph has been stopped, the carri'age 15 can be moved backto the starting point and the pictures repeated or a new picture diskattached.

The carriage 15 is supported by a roller 23, pivoted in a yoke formed inthe fran'le, which rolls on the top of the frame 2' forming a tracktherefor. The frame has at its forward end a bifurcated arm 24, bent ata right angle therewith into which the picture disk revolves. To theouter part of said arm is attached a projecti lens 25 and to theopposite part an electrlc lamp 26 with a suitable reflector. The lampmay be supplied with electric energy from any suitable source, such as abattery.

vious that the motion transmitted to the rocking arms, will cause thedisks 1* and t to move in unison with an irregular step by step motion.When a record is to be exhibited, the carriage 15 is placed to theextreme right with on pin of the rocking arm engaging a hole in themaster disk. As the phonograph is started, the pins inthe rocking armswill alternatively engage the holes in the master'difsk, causin the sametoirotate. The pins will engage t e holes in the spiralpathalternatively and cause the carriage 15 with its lens and lamp tomove in a rectilinear path toward the center of its axis. By reason ofthe peculiar formation of the cam 'w' it will b seen that it takes acomplete revolution'of the camshaft to effect a change from one pictureto another. The cam will bring the picture into and allow the same toremain in the illuminated field for a predetermined time, the intervalof the exposure being greater than the time required t9 effect a change.7 n

. Owing'to the t number of pictures on a disk, lt'may i e necessary torepeat the 'music several times over, while the pictures are exhibited.This may be accomplished toward the opposite side. It will beunderstood, that the apparatus must be operated in a darkened room. Thepictures are pro jected onto the translucent screen froma positive withopaque background and must e viewed by the audience at the other side ofthe screen. In other words, the lens moves in a radial line always atthe same distance relative-to the picturedisk beginning at its greatestradius or outer convolution of pictures and terminating at theconvolution adjacent to the axis of the disk.

I claim 1. In a moving picture machine, the combination with a diskhaving pictures in spiral formation thereon, -means for intermittentlyrotating the disk; of a master disk connected to the picture disk, means"for moving the master disk in unison with the picture disk, and aimsactuated by the master disk.

2. In a moving picture machine, the combination with a disk havingpictures in spiral formation thereon .means for intermittently rotatingthe disk; of a master disk connected to the picture disk, means forrotating the master disk in unison with the picture disk, and a lensactuated by the master disk in a rectilinear line with the radius of thepicture disk.

3. In a moving picture machine, the combination with a disk havingpictures in spiral formation thereon means for intermittently rotatingthe disk; of a master disk having perforations in spiral formation,means coacting with the perforations connected to the driving devicesfor rotating the disk in unison with the picture disk, and a lensactuated by the master disk in rectilinear line with the radius of thepicture disk.

4. In a moving picture machine, the combination with adisk havingpictures in spiral formation thereon, means for intermittently rotatingthe disk; of a master disk having perforations in spiral formation,means coacting with the perforations connected to the driving devicesfor alternatively interrupting and oscillating the Fdisk in unison withthe picture disk, and a lens actuated by the master disk in arectilinear line with the radius of the picture disk. r
